Reductive leaching of ilmenite ore in hydrochloric acid

The reactivity of ilmenite ore during leaching with hydrochloric acid can be greatly enhanced by reduction in solution using metallic iron. Addition of a particular amount of iron powder after a certain time of reaction will reduce all the dissolved Fe 3+ to Fe 2+ and reduce a portion of the dissolved Ti 4+ to Ti 3+.As the leaching continues, any further dissolved Fe 3+ will be simultaneously
